The Sabbath was never part of the ceremonial law. There were additional sabbaths that were but the 7th day Sabbath commemorating Creation was never part of that. The 7th day Sabbath is part of the TEN (count them) COMMANDMENTS (not suggestions).

Rom 14:5 In the same way, some think one day is more holy than another day, while others think every day is alike. You should each be fully convinced that whichever day you choose is acceptable.
Observance of the Sabbath was never enjoined until the Law, and as shown, under which the Spirit treats the Sabbath as part of the ceremonial law, despite assertions to the contrary made in the light of and the utter absence of the 4th commandment being repeated/reiterated while doing so for the rest, nor providing and one example of any NT church doing so.

There is none, only a precedent of meeting on the first day under the New Covenant, the only specific day they are shown meeting on, which you lack, while the principle of one day of rest based on God's rest (from His atoning mission) supports this practice.
I myself after becoming a Christian (former RC) have never worked for money on the first day (Sat, even to Sun, eve) even when I used to work 6 long days a week, and refrain from personal recreation on that day, as sanctified, nor do i condemn those who hold that 7th day is the correct day, as long as the motive is to honor the Lord.
But mandating observance of the 7th day even relegating those who do not to being demonically deceived damned souls as you have done, is what i contend against. Thus it is your cultic spirit that makes your salvation suspect.
